Shaped Brick

ABSTRACT

The invention relates to a shaped block for forming a wall or a retaining wall. The shaped block includes a body (K) and wings (F) arranged on the body that are oriented toward laterally adjacent shaped blocks. The shaped block (S) has a left wing (F, FL) and a right wing (F, FR) which are arranged in front of or behind a vertical plane (E), which divides the shaped block (S) at the half shaped block depth into a front half (SHV) and a rear half (SHH). The wings (F; FL, FR) are arranged offset with respect to one another by at least one wing depth.

FIELD OF THE INVENTION

The invention relates to a shaped block for forming a wall or aretaining wall.

BACKGROUND OF THE INVENTION

CH 687 394 discloses a shaped block, which includes a body and wingsarranged at two opposite sides of the body. A disadvantage with theknown shaped block is that, when it is used to construct straight walls,the known shaped block only allows the construction of walls, which haveopenings toward one side and whose structure is weak in the region ofthese openings. A further disadvantage is that the known shaped blockdoes not permit any length compensation when used to construct walls orretaining walls, thereby requiring that known shaped blocks have to belaboriously shortened in order to obtain dimensions which do notcorrespond to an even multiple of the known shaped block unit spacing.

The object of the present invention is to develop a shaped block bymeans of which stable straight walls can be constructed and which allowslength or radius compensations during the construction of walls andretaining walls.

SUMMARY OF THE INVENTION

The shaped block according to the invention is equipped with a left wingand a right wing that are both arranged in front of, or which are botharranged behind, a vertical plane. The plane divides the shaped blockinto two halves. The wings are arranged offset with respect to oneanother by at least one wing depth. The offset arrangement of the wingsmakes it possible for adjacent shaped blocks to be arranged next to oneanother with their wings partially or completely overlapping. Firstly,this increases the stability of the wall since the whole wall or atleast some of it has a thickness in the transition region of twoadjacent shaped blocks that corresponds to a double wing depth. Inaddition, the offset wings enable adjacent shaped blocks to be arrangedat different spacings from one another and the wall length to be variedas a result. By lining up the shaped blocks such that they arealternately rotated through 180° about a vertical axis, it is possibleto construct walls in which the wings of adjacent shaped blocksrespectively lie in front of and behind the vertical dividing plane andthus stabilize the wall particularly well. The essence of the inventionis a body comprising laterally arranged wings, whose offset arrangementin front of or behind a mid-plane oriented parallel to the visible faceof the shaped block allows adjacent shaped blocks to have a large numberof positioning options. These positioning options include not only theoption of allowing the shaped blocks in a wall layer to follow oneanother at various spacings while not having to accept any losses interms of the wall quality, but also the option of joining together theshaped blocks in various orientations—yawing (rotation about a verticalaxis) through 180°—and of making it possible thereby to produce walls ofdifferent structure and different appearance.

The invention provides a form-fitting and/or frictional interactionbetween the wings of adjacent shaped blocks so as to impart a highdegree of intrinsic stability to the wall to be formed by virtue of theshaped blocks actively supporting one another.

Furthermore, the invention provides that the left wing and the rightwing are formed with identical dimensions. Given the offset provided,this allows optimum interaction between the wings.

The invention particularly provides that the left wing is formedpoint-symmetrically with respect to the right wing. This simplifies theconstruction and leads to the two wings having comparable loadability.

According to the invention, the shaped block is made of concrete so thatit can be produced cost-effectively in large quantities.

Furthermore, the invention provides that a cavity is formed between thebodies of adjacent shaped blocks and their wings, for which purpose thetwo wings are at a distance from one another or are offset with respectto one another by more than one wing depth, or have at least one recess.This cavity results in further stabilization of the wall and also allowsconcrete, mortar or soil to be introduced therein.

The invention provides that the wing is formed with at least oneprojection and/or at least one recess. This makes possible aform-fitting interaction, such as an interlocking, for example, betweenthe shaped blocks.

A particular embodiment provides that the projection or the recess isformed on a free end of the wing. This allows force to be introduceddeep into the adjacent shaped block, thereby permitting the transmissionof considerable forces between the adjacent shaped blocks.

Furthermore, the invention provides that at least one projection or onerecess is formed on the body. This configuration also allows a form fitbetween a wing and a body of an adjacent shaped block and increases thestability of the wall.

The invention particularly provides an interaction between theprojection or the recess of the wing and the recess or the projection ofan adjacent body in order to increase the stability of the wall.

Likewise, the invention provides an interaction between the projectionor the recess of the wing and the wing of an adjacent shaped block inorder to increase the stability of the wall.

Provision is made according to the invention for the body of the shapedblock to be formed, in plan view, as a rectangle, square, triangle,circle, ellipse or trapezoid. This makes it possible to erect walls ofwidely varying appearance that have all the advantages of the invention.

Furthermore, the invention provides that the shaped block be provided inthe region of its body with at least one vertical opening extending froman upper side to a lower side of the shaped block. This makes itpossible for the weight of large shaped blocks to be kept within limits.

The invention also provides an opening which tapers toward the lowerside of the shaped block. From a manufacturing point of view, such anopening can be produced simply using a block-molding machine since thereis a large draft angle.

Furthermore, the invention provides that lugs are arranged on an innerface of the opening. As a result, the shaped block has supports whichallow the fastening and installation of fittings.

The invention provides that at least one slab is inserted into theopening so that the opening can be at least partially closed. This makesit possible, for example in the case of retaining walls, to direct theroots of plants into the embankment.

The invention provides that the opening is closed in the shaped block atan upper side and/or at the lower side of the shaped block. Closing itat an upper side permits a simple termination of the uppermost blocklayer of a wall. By closing a wall block at the top and bottom, it iseasily possible to provide a region in an embankment that is selectivelyfree from vegetation.

The invention also provides support ribs which are formed on the body ofthe shaped block toward laterally adjacent shaped blocks. This providesan increased bearing surface for a shaped block of a wall layer situatedimmediately above, this bearing surface increasing the stability of thewall.

According to the invention, a predetermined breaking point is providedbetween the wing and the body so that corners or wall terminations inwhich the wing is not necessary can be formed with little effort.

Finally, the invention provides dimensioning the wing with a width whichlies between ⅓ and ¾ of the body width. Such a wing-body ratio alsoallows considerable length compensation without having to surrender asufficient overlapping of the wings.

For the purposes of the invention, the term “wing” is to be understoodas a continuation whose width (EB) is greater than its depth (FT). Forthe purposes of the invention, a distinction should be drawn betweenthis and a protrusion in which the width (FB) is less than the depth(FT). FB>FT applies in principle for the wings of the shaped blocksaccording to the invention.

DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 to 3 show three variant embodiments of a first shaped block Saccording to the invention in a perspective representation. The shapedblock S essentially comprises a body K and two wings F, which are alsoreferred to below as left wing FL and right wing FR. In plan view thebody K has the contour of a rectangle R. The shaped block S or the bodyK is divided by a vertical plane E into a front half SHV and a rear halfSHH. Here, the plane E is arranged centrally between a first visibleside 1 and a second visible side 2 of the shaped block S. Based on ashaped block depth ST, the plane E thus has a spacing from both thefront visible side 1 and from the rear visible side 2 that correspondsto a half shaped block depth HST=0.5×ST. The wings F are arranged on aright side face 3 and a left side face 4 of the shaped block S, extendapproximately parallel to the plane E and, since with each having a wingdepth FT, a wing width FB and a wing height FH, have identicaldimensions. A front side 21 of the right wing FR lies together with thevisible side 1 of the shaped block S in a common plane E1, which isparallel to the plane E. A front side 8 of the left wing FL is set backfrom this plane E1 in the direction of the plane E. The shaped block Shas, apart from the shaped block depth ST, a shaped block width SB and ashaped block height SH, the shaped block depth ST corresponding to abody depth KT and the shaped block height SH corresponding to a bodyheight KH. Finally, the shaped block width SB is the sum of the two wingwidths FB and a body width KB. The shaped block S is delimited at thetop and bottom by an upper side 5 and a lower side 6. Wings F or FL andFR arranged laterally in the front half SHV of the shape S arecharacteristic of the shaped block S. These wings are at a distance DFfrom one another in the y-direction, the distance DF being measuredbetween a rear side 7 of the right wing FR and the front side 8 of theleft wing FL. The wings FL and FR are point-symmetrical with respect toa point of symmetry SP. Optionally, edges K1 and/or K2 at which thewings F merge into the body K are provided, as predetermined breakingpoints S1, S2, with a notch (not shown here) so as to make it easier, atthe ends of walls, to cut off a wing F which is not required.

The shaped block S represented in FIG. 1 is configured as a solid block.The shaped blocks S represented in FIGS. 2 and 3, although havingidentical dimensions and an identical external shape, differ therefromin that they each have a vertical opening 9 which traverses the shapedblock S from the upper side 5 to the lower side 6. In the variantembodiment of the shaped block S represented in FIG. 2, the opening 9tapers in an arrow direction z′ in the manner of an inverted truncatedpyramid.

In the third variant embodiment of the shaped block S represented inFIG. 3, the opening 9 is cuboidal in shape. Four lugs 10 are arranged oninner walls (without reference signs) of the opening 9 and serve assupports 11 for a slab 12 which can be inserted into the opening 9. Thepositioning chosen for the lugs 10 allows the opening 9 of the shapedblock S to be closed off toward its upper side 5. This is particularlyadvantageous in the case of the uppermost layer of a wall of shapedblocks S, since a relatively neat wall termination is thus possible withlittle effort. Of course, the invention also makes provision to arrangethe lugs close to the lower side 6 of the shaped block S so as to makeit possible to delimit the opening 9 at the bottom using the slab.

The variant embodiment of the shaped block represented in FIG. 2 alsoallows slabs to be inserted at different heights (z). For this purpose,it is possible for example to use slabs formed as truncated pyramids.Analogously to the variant embodiment shown in FIG. 3, provision is alsomade to provide the opening with lugs or shoulders which can serve assupports for slabs or other inserts, such as baskets or water storagemeans, for example.

FIG. 4 shows a left shaped block SL, a central shaped block S and aright shaped block SR in a perspective representation. The shaped blocksSL, S, SR are arranged next to one another and form part of a wall layerML of a wall M. The shaped blocks SL, S, SR represented in FIG. 4correspond in terms of their dimensions to the shaped block known fromFIG. 1. All three shaped blocks SL, S, SR are arranged in the sameorientation. Consequently, the wings F are situated in front of theplane E which divides the shaped blocks SL, S, SR. FIG. 4 shows a planeE for each of the shaped blocks SL, S, SR, these individual planes E, ofcourse, forming a common plane when the wall M is formed straight. Theoffset arrangement of the wings F means that the wing FR of the shapedblock S and the wing F of the shaped block SR, and the wing FL of theshaped block S and the wing F of the shaped block SL, each lie parallelto one another in front of the plane E. Hence, the wall M or the walllayer ML is also formed solidly, and thus stably, between the bodies Kby virtue of a double wing arrangement. In the arrangement of the shapedblocks SL, S, SR shown in FIG. 4, the side faces 3, 4 of the shapedblocks SL, S, SR and the wings F enclose cavities 13. These have a depthT13 which corresponds to the distance DF represented in FIG. 1.

FIG. 5 shows a plan view of a second shaped block S. This is similar indesign to the shaped block shown in FIG. 1, but here, wings F or FL andFR are offset with respect to one another in the y-direction by only onewing depth FT and thus, unlike the shaped block known from FIG. 1, donot have any distance from one another. Analogously to the shaped blocksrepresented in FIGS. 2 and 3, the shaped block S has an opening 9. Thetwo wings F are arranged in front of a plane E which divides the shapedblock S or its body K.

FIG. 6 shows a third shaped block S in which wings F or FL, FR aresituated in front of a plane E which divides a body K. By contrast withthe shaped blocks shown in the preceding figures, the wings F haveprojections 15 on free ends 14. The wings FL and FR have a distance DSfrom one another.

FIGS. 7 a to 7 c are plan views showing different wall layers ML whichare formed by shaped blocks S which correspond to the shaped blockrepresented in FIG. 5. By way of example the individual wall layers MLare each formed by a left shaped block SL, a central shaped block S anda right shaped block SR.

The individual wall layers ML have different lengths L1, L2, L3, whereL1<L2<L3. These differences are determined by a different degree ofoverlapping between the wings F of adjacent shaped blocks SL, S or S,SR. In the wall layer ML represented in FIG. 7 a, not countingtolerances, the wings F overlap one another virtually completely, sothat the degree of overlapping can be said to be approximately 100%. Theshaped blocks SL, S, SR of the wall layer ML represented in FIG. 7 bhave a degree of overlapping of approximately 50%, since the wings F areeach situated in front of or behind one another by approximately half awing width FB. In the wall layer ML represented in FIG. 7 c, the degreeof overlapping, being approximately 25%, is at a lower limit.

FIGS. 8 a to 8 c again show three different wall layers ML which areeach composed of two shaped blocks SL, S which correspond to the shapedblock described in FIG. 6. As far as the matter of the lengths of thewall layers and the degree of overlapping is concerned, reference shouldbe made to the comments pertaining to FIGS. 7 a to 7 c. As FIG. 8 cshows, the projections 15 on the free ends 14 of the wings F prevent thepossibility of falling below a minimum degree of overlapping, sincethese projections would only allow a further parting movement of theshaped blocks S and SL if one of the shaped blocks S, SL weresimultaneously displaced in the y-direction. FIGS. 8 a and 8 b show howa cavity 13 enclosed between the wings F also decreases in volume as thedegree of overlapping decreases. In the wall layers ML represented inFIGS. 8 a to 8 c, the shaped blocks S, SL involved are always placed inthe same orientation next to one another.

FIG. 9 a shows a plan view of a fourth shaped block S which is similarin configuration to the shaped block represented in FIG. 6. The shapedblock S essentially comprises a body K and wings F or FL and FR arrangedthereon.

In FIG. 9 b, a first wall layer ML comprising three shaped blocks SL, S,SR is represented. These shaped blocks SL, S, SR, like the shaped blocksof the wall layers represented in the preceding figures, are all laidout with the same orientation so as to generate a smooth wall pattern ata visible side 1, all the wings F being situated in front of the plane Ein the y′-direction. At a second visible side 2 which may be present(free-standing wall), the wall layer ML has recesses 16 alternating withthe bodies K.

FIG. 9 c shows a further wall layer ML containing four shaped blocks SL,S, SR, SRR, in which the shaped blocks S and SRR are arranged with theknown orientation. The remaining shaped blocks SL and SR are rotatedthrough 180° with respect to the shaped block S, the rotation takingplace about a vertical axis H which emerges vertically from the plane ofthe drawing. To make the description of the wings F of the shaped blocksSL, S, SR, SRR clearer to understand, a distinction will now be drawnbetween wings FF which are remote from the plane E and wings FN whichare situated close to the plane E.

The various transitions between adjacent shaped blocks SL, S or S, SR orSR, SRR are now defined by the interaction between two wings FF remotefrom the plane E or by the interaction between two wings FN close to theplane E. If two wings FF interact, the resulting impression is of arecess-free wall section M1 at both visible sides. If two wings FNinteract, the result is a wall section M2 which has recesses 16 at bothvisible sides.

The third design variant has already been represented in FIG. 9 b. Thisis obtained by the interaction of a wing FN close to the plane E with awing FF remote from the plane E. There results a wall section M3 whichhas a recess 16 at only one visible side of the wall.

Depending on the particular system, it is possible using the shapedblock according to the invention to form either wall layers which arecomposed continuously of wall sections M3 or in which wall sections M1and M2 alternate or in which wall sections M1, M2 and M3 alternate.

In particular, the formation of a wall which is built up from wallsections M3 also allows the formation of arcuate retaining walls.

FIG. 10 shows a plan view of a retaining wall M made up of shaped blocksS, the shaped blocks S corresponding to the shaped block shown in FIG. 9a. The wall M comprises a lower wall layer ML1 and, set back from this,a wall layer ML2. Adjacent shaped blocks S of the lower wall layer ML1are each rotated with respect to one another through an angle α=15°about a vertical axis rising vertically from the drawing. Whenconsidered in an idealized manner, the shaped blocks S of the lower walllayer ML1 describe an arc (not shown) having a radius R1. On account ofthe upper layer ML2 being set back from the lower wall layer ML1, theupper wall layer ML2 when considered in an idealized manner describes anarc (not shown) having a radius R2, where R1>R2. The shaped blocks S ofthe upper wall layer ML2 are each rotated with respect to one anotherthrough an angle β, it also being the case in principle, given thesmaller radius R2, that α<β. Such a structure of the retaining wall M isonly possible if the degree of overlapping of interacting wings Fincreases from the lower wall layer ML1 to the upper wall layer ML2.

Finally, FIG. 11 shows a plan view of a fifth shaped block S which hasprojections 17 and recesses 18 on visible sides 1, 2 and on side faces3, 4 of its body K. Projections 15 are also formed on free ends 14 ofwings F or FL, FR. The wings F are situated in front of a plane E whichdivides the shaped block S in half and extends perpendicularly into theplane of the drawing. The shaped block S is divided by the plane E intoa front shaped block half SHV and a rear shaped block half SHH. Thewings FL and FR formed in the front shaped block half SHV are arrangedoffset with respect to one another and have a spacing DF from oneanother, the projections 15 arranged on the free ends 14 bridging thisdistance DF if wings F of adjacent and identically oriented shapedblocks S interact. Furthermore, the shaped block S has an opening 9which extends from an upper side 5 to a lower side (without referencesign). Similarly to an inverted truncated pyramid, the opening 9 hasinclined inner faces 19 of which two merge into a shoulder 20. Onto theshoulders 20 can be deposited a slab 12 which partially closes theopening. According to a variant embodiment which has not beenrepresented, provision is made to form further shoulders on the inclinedinner faces and thus make it possible to insert a plurality of slabs atdifferent levels. Provision is made in particular for the shaped blockto be closed off at its lower side and at its upper side using a slab.The recesses 18 arranged on the side faces 3, 4 in FIG. 11 aredimensioned such that the free ends 14 of shaped blocks S are rotatedthrough 180° with respect to one another enter these recesses, resultingin a form-fitting retention of adjacent shaped blocks S. Here, therecess 18 is arranged on the side face 3 alongside the wing FR or FNclose to the plane E, the recess being intended to accommodate a winglikewise close to the plane E that belongs to a neighboring block (notshown). Conversely, the recess 18 is arranged on the side face 4alongside the wing FL or FF remote from the plane E, this recess beingintended to accommodate a wing likewise remote from the plane E thatbelongs to an adjacent block (not shown). The recesses 18 arranged onthe visible sides 1, 2 make it possible, in the case of right-angledwall runs for the leg of an adjacent shaped block, to be supported in aform-fitting manner. When considered in an idealized manner, the body Khas the contour of a trapezoid T in plan view.

FIG. 12 shows a further shaped block S in plan view. In this shapedblock S the two wings FL, FR are set back from a visible side 1 of theshaped block S. A front side 8 of the left wing FL has an offset V1 fromthe visible side 1, and a front side 21 of the right wing FR has anoffset V2 from the visible side 1.

FIG. 13 shows a plan view of a wall M made up of five shaped blocks SLL,SL, S, SR and SRR. The shaped blocks SL and SR are laid by each beingrotated through 180° about a vertical axis H with respect to the shapedblocks S, SLL and SRR, in which arrangement wings FL, FR of adjacentshaped blocks SLL, SL or SL, S or S, SR or SR, SRR respectively bearagainst one another with their front sides 21 or rear sides 22.Provision is made in particular in such a wall M for the shaped blocksSLL, SL, S, SR and SRR to be formed as stakes so as to be able to form awall run tailored to unevenly terminating ground.

The invention is not limited to exemplary embodiments which have beenrepresented or described. Instead, it covers developments of theinvention within the scope of the claims. In particular, the inventionalso makes provision to form the body, in plan view, as a polygon withstraight and/or rounded sides. Furthermore, the invention makesprovision to form the body as a stake.
